Actually, there's an option to manipulate the market price, just like how whales are doing it, but not the market in totality. It's highly improbable. But when it comes to market price manipulation, it is possible if you have a fat account. We know it for a fact that money is power. If you have the money to acquire vast quantity of coins which you desire to manipulate, then you can sway it to your preferential price. But if you do not have, I suggest, buy bitcoin at its dip and hodl, and yeah, it's still worth it. You'll see what I mean in the coming months.
